我尝试做什么：
Call function1 => set values
Call function2 => GetValues
Sysout => print the modified values
我的问题，sysout来了，我做了＆＃34; Set Values＆＃34;所以它向我展示了旧的价值观。
我做错了什么？
这是我的代码：
System.out.println("Cmd before SetParam : "+info1+"/"+info2+"/"+info3+"/"+info4+"/"+info5+"/"+info6+"/"+info7+"/"+info8);
TMSSA2_1.SetParam(info1,info2,info3,info4,info5,info6,info7,info8);
String[] cmd = new String[8];
cmd = TMSSA2_1.GetCmd();
System.out.println("New Cmd => "+Arrays.toString(cmd));
所以我的输出看起来像：
cMD before SetParam : 45/128/128/128/128/128/0/0
New Cmd => [null, null, null, null, null, null, null, null]
SetParam => ok
GetCmd => Ok
所以你可以看到我的2个函数在我的sysout之后调用。
